Answer: OPTION D

Step-by-step explanation:

The formula for calculate the surface area of a rectangular prism is:

[tex]SA_{rp}=2(wh+lw+lh)[/tex]

Where w is the width, h is the height and l is the length.

You can see in the figure attached that:

l=3.4ft

w=3ft

h=4.1ft

Therefore, when you substitute these values into the formula you obtain that the surface area is:

[tex]SA_{rp}=2[(3ft*4.1ft)+(3.4ft*3ft)+(3.4ft*4.1ft)]=72.88ft^{2}[/tex]
